Geom::PathVector	doEffect_path (Geom::PathVector const &path_in) override

void	doBeforeEffect (SPLPEItem const *lpeItem) override
	Is performed each time before the effect is updated.

void	doOnApply (SPLPEItem const *lpeitem) override
	Is performed a single time when the effect is freshly applied to a path.

void	doOnRemove (SPLPEItem const *lpeitem) override

void	doAfterEffect (SPLPEItem const lpeitem, Geom::PathVector curve) override
	Is performed at the end of the LPE only one time per "lpeitem" in paths/shapes is called in middle of the effect so we add the "curve" param to allow updates in the LPE results at this stage for groups dont need to send "curve" parameter because is applied when the LPE process finish, we can update LPE results without "curve" parameter.

void	transform_multiply (Geom::Affine const &postmul, bool set) override
	Overridden function to apply transforms for example to powerstroke, jointtype or tapperstroke.

Is performed at the end of the LPE only one time per "lpeitem" in paths/shapes is called in middle of the effect so we add the "curve" param to allow updates in the LPE results at this stage for groups dont need to send "curve" parameter because is applied when the LPE process finish, we can update LPE results without "curve" parameter.
